Go ahead and learn how to read and write music, Sir Paul. It won’t hurt your talent one little bit, and you might find you’ll get more inspiration from the simple act of putting the notes on paper. I promise you it’s happened before.
Pliable, of On An Overgrown Path, has some suggestions for Sir Paul and Sting regarding their recent efforts in "classical" music:
If Paul McCartney really wanted to put communication centre stage he could have underwritten a performance of a little known and deserving contemporary choral work (let's take Rudolf Mauersberger's sublime Dresden Requiem as an example) in London, he could have made sure the hall was full by promoting it in the media, and he could have persuaded his record company, EMI, to record and really market the results. That way new audiences would have experienced real creativity, conviction and communication. Meanwhile [Mr.] Sting could have put his efforts behind persuading (and funding) an online archive of the BBC's contemporary music riches similar to that hosted in Finland by YLE, and he could have persuaded some of his super-rich rock buddies to fund the first year's composer royalties to allow free downloading - now that would be breaking the mould.
